It is narrated from Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) that a man from Bahrain came to the service of the Prophet (peace and blessings of Allah be upon him) and greeted him with salam, but the Prophet (peace and blessings of Allah be upon him) did not reply to his salam. This was because he had a gold ring on his hand and was wearing a silk cloak. The man left in distress and went to his wife and told her. She said: Perhaps the Messenger of Allah (peace and blessings of Allah be upon him) was displeased with you because of your cloak and ring, so take them off and go back. He did so, and the Prophet (peace and blessings of Allah be upon him) replied to his salam. He said: I just came before and you turned away from me? The Prophet (peace and blessings of Allah be upon him) said: "There was a burning coal in your hand." He said: Then I have brought many coals. The Messenger of Allah (peace and blessings of Allah be upon him) said: "What you have brought (here) is of no more value to anyone than the stones of a stony land. But it is a provision of worldly life." He said: Then what kind of ring should I wear? The Prophet (peace and blessings of Allah be upon him) said: "Wear a ring of silver, brass, or iron."
